In the angle be doubled to 2 α.Due to the non-linear nature of lens 63, when second mirror 68 is in first position, printing beam 14
It is incident on away from lens axis location of C on product 22.But when second mirror 68 is in second position, although angle
Increase to 2 α, printing beam 14 can not be still incident on product 22 away from lens axis 2C positions.The non-linear nature of lens 63 is led
Cause to lack proportionality between the movement of mirror 68 and the movement of printing beam 14.
Electronic component 26 (Fig. 1 Β) can include the logic components of the non-linear effect of second positive lens 63 of correction.Accordingly
Ground, the logic components, it is that printing beam 14 is moved by 2C, second mirror 68 can be caused to increase above 2 α angle.It is in addition, different
Relation is also possible.Correcting logic part can be from the theoretical optics for providing relation between C and α for second positive lens 63
Equation is developed.The specific geometry of optics control subsystem, such as mirror and their setting, can be included in theoretical mould
In type.Alternatively, correcting logic part can from be executed to determine α and C between relation experimental development.The correcting logic part disappears
Except the needs for being used for correction of Nonlinear, expensive and big F lens to typical case.Correspondingly, the correction allows to reduce and printed
The size and cost of system 10.
Spherical aberration effect can be corrected by the variable residence time.For example, it is obvious on product 22 to work as aberration effect
When, the residence time can be increased.
In the operating process of the optical building elements 18 including printing zone light source 52, activation printing zone light source 52 simultaneously stops
Only laser 12.Mobile mirror 62 is so as to the formation printing zone 34 on product 22.When to form symbol in packaging, release
Printing zone light source 52, and using laser/energy source 12 until forming symbol.Once forming symbol, laser/energy can be released
Source 12 simultaneously uses printing zone light source 52, so as to continuously form printing zone 34.
Such as reference chart 1B discussion above, print system 10 can include with the printing beam that relative device shell 16 moves can going out
Mouth part 32.Fig. 4 C and 4E show the machinery setting for allowing printing beam outlet member 32 to carry out this movement.Framework 76 in Fig. 4 C exists
Supporting printing beam outlet member 32 in shell 16.The bearing 78 being positioned between framework 76 and printing beam outlet member 32 allows printing beam
Outlet member 32 moves relative to framework 76.Fig. 4 E provide the side cross-sectional view that bearing 78 is observed along printing beam 14.The edge of printing beam 14
By the rotation axis 80 that bearing 78 (Fig. 4 E) allows by bearing 78 (Fig. 4 C and 4E), reflected by mirror 62 (Fig. 4 C) and by going out
The end of mouth part 32 (Fig. 4 C and 4E).Therefore, printing beam outlet member 32 does not change the phase of printing beam 14 relative to the movement of framework 76
For the position of bearing 78.
As shown in Fig. 4 C and 4E, mirror 62 and actuator 70 couple with printing beam outlet member 32.As a result, when printing
When the opposite shell 16 of beam outlet member 32 moves, mirror 62 and actuator 70 move together with printing beam outlet member 32.In addition, first
Rotation axis 80 (Fig. 4 E) positioning of the part (Fig. 4 B) for individual mirror 66 along bearing.Therefore, the movement of printing beam outlet member 32
The incident angle between printing beam 14 and first mirror 66 is not changed.Correspondingly, when the opposite shell 16 of printing beam outlet member 32
When mobile, first mirror 66 still guides printing beam 14 to a same part for second mirror 68, and printing beam 14 is yet by protection
The same section of window 64 leaves shell 16.It is logical that the rotatability of the opposite shell 16 of printing beam outlet member 32 allows printing beam 14 to launch
Cross each position that printing beam outlet member 32 comes on aimed product 22.
As described above, printing beam 14, changed by the optical characteristics remained in position until the position, in product 22
Each position on form multiple spots.For showing purpose, Fig. 5 A -5D are shown by removing ink layer from product 22 and in product
Spot is formed on 22.Fig. 5 A and 5B are shown, before forming spot 83 (Fig. 5 C) on material 20, are incident on material on location
Printing beam 14 on 20.Material 20 includes stock 82, such as paper.Ink layer 84 is formed on stock 82.Ink layer 84 can
With including some different ink types and some different colors, as the label of many available commercial products 22
It is clear.The material 20 shown in Fig. 5 A includes additional layer 86.Additional layer 86 represents typically occurs in ink layer in product packaging
The one or more of 84 tops.For example, many materials 20, such as dog food bag, including stock 82 and the wax of the top of ink layer 84
Layer.
Fig. 5 C -5D show to form after spot 83 material 20 shown on the ad-hoc location of material 20.So regulation print
Brush bundle 14 stops the time on location, so as to printing beam 14, in the case where not burning stock 82, melts ink layer
84 and the additional layer 86 of material 20.As a result, stock 82 can be seen on the ad-hoc location of material 20.Melt ink layer 84
Time typical case be 100-500us.
The time for forming spot 83 is typically the function of material 20 in layer.For example, additional layer 86 can be protective packaging simultaneously
Wax layer to the appearance that it attracts.Spot 83 is formed by this layer and usually requires the time more than only ink layer 84 needs.
The application stops the time in position including regulation printing beam 14, so as to form spot on the position.One
In a little examples, the residence time is more than 50 μ s, such as 100 μ s, 200 μ s, 50-50000 μ s, 100-500 μ s or 200-500 μ s.
In some examples, spot diameter is less than 400 μm, less than 250 μm or less than 170 μm.
Fig. 6 shows traditional font defi-nition 600 of alphabetical " A ".Mark quality includes the subjective evaluation of character shape.For dividing
The existing laser font that step repeats laser marking system forms the character for showing low resolution dot matrix printing machine.This laser mark
Note system marks are arranged on the pixel on lattice pattern to form character：Welcome is 5x7,7x9,11x9 and 13x9 fonts.This
For a little fonts from the video sequence of adjacent pixel, diagonal sequence or vertical series form character.For example, traditional font defi-nition 600
Illustrate how only to form diagonal at 45 °.Short 45 ° of part 602 and vertical or horizontal part 604,606 alternate form
Other angles.This causes jagged diagonal and the poor curve of formation, and the diagonal and curve are reduced for alphabetical number
The visual quality of word character laser labelling.
When marking big character, the obvious and adjacent spot of each spot is not overlapping.But many clients mark is smaller
Character and adjacent pixel are really overlapping in most application.When adjacent pixel is overlapping, due in conventional laser font
Amplified version in distance (two square root is multiplied by horizontally or vertically the distance between pixel) larger between diagonal pixels,
The dosage of overlapping region is delivered to for diagonal pixels than for horizontally or vertically pixel few up to 40%.Overlapping amount is got over
Greatly, the influence is more important.For coherent mark quality, dosage enough should mark diagonal.That means that client should
Using than it is horizontal and vertical mark need dosage more than up to 40%.For the stock of sensitivity, such as thin layer is packed, this increase
The risk penetrated.When being printed with a size, although font pixel may be overlapping, but not it is printed with another size
.It can cause inconsistent printing using various sizes of same font (they will not effectively be scaled).
Partly to improve the continuity and quality of laser labelling, scalable laser font is introduced.Maintained with it and
User is set to use multiple, single font (for example, 5x7,7x9,11x9 and 13x9 font), independent scalable font can replace
These multiple fonts simultaneously can easily be converted into suitable pixel compartments based on character size and quality settings as needed.This can
To cause the indicia appearance improved, while reduce the risk that stock penetrates, it is especially useful in packaging thin layer.Penetrating reduces thin layer
Integrality, performance can simultaneously have a negative impact to the product of client.Packaging thin layer represent packaging industry it is huge and increase
Part, thin layer penetrates the workability that can limit laser marking system in the field.
Fig. 7 is shown with the result for the laser labelling that traditional font defi-nition and new scalable font defines.It can set
Laser marking system is counted to support the font for enabling font design person to avoid marking the high-resolution of adjacent pixel.For example,
Consider the character that mark 2mm is high, 1.2mm is wide.11x9 font tags with 0.16mm perpendicular separations and 0.12mm horizontal intervals,
These intervals can be less than the nominal 0.180mm spot sizes of system.These marks are overlapping and form continuous line.Diagonal mark
Note interval 0.22mm, higher than nominal spot size, does not re-form continuous line.
Using twice, the 40x25 fonts of pixel count that are unanimously spaced avoid the problem.In location of pixels is selected, compared with
High resolution ratio provides higher flexibility, it is allowed to font design person more consistent ground spaced pixels, while double pixel count permission
The character shape visually more attracted.The residence time can be reduced to compensate increased pixel count.In this example, with 7x5 words
The half of the residence time of body 702 marks high-resolution font 704, but marks the number identical with laser energy consumption.Shown as one
The pixel separation of cause produces more coherent mark, and allows the wind that user reduces laser energy consumption and thing followed thin layer penetrates
Danger.
To solve the problems, such as to maintain the multiple fonts not scaled, new font defi-nition is introduced.This definition replaces definition independent
Pixel, and each part of definition character, here part can include straight line, curve and point.In job design, Yong Huke
With the character size and quality (for example, pixel separation) of regulation printing.Information based on the part, obtain the mark of correct interval
Position to form intended size, the character of correct quality.This allows independent font pantograph to any size and produced with big
The dot matrix printing at interval, or closely-spaced produce aesthetic more comfortable printing with consistent.Furthermore, it is possible to determine to use in advance
Protect in the given font marked and dimension information and in the project document with the tagging items run later on assembly line
Deposit these information, font defi-nition allows the last change for setting printing quality (while to maintain from the identical of identical items document
Font), realize for compromise of the speed for giving laser labelling project operation with respect to printing quality.

Family interface 30 inputs.Software 802,804 can store on a machine-readable medium, for example, hard disk driver, CD or memory.Software
802 may be embodied in printer driver, for example, MicrosoftPrinter driver.It also will be understood that
The feature operation of description may be embodied in multiple software product, and example is as described in those software products, or individually software production
In product, multiple operating systems can also be used.
Laser printing system (LPS) 810 can have 2 " x4 " laser hole, spot size 0.008 " and minimum substep time
150μs.Optical maser wavelength and energy consumption can determine can be by the material of image mark.Image print system 820 based on laser

To be sliding block graphical user interface (GUI), or other inputs, such as numeral input, classification input, or the persistent value based on GUI
Input.In addition, quality settings information (for example, default quality setting) can be stored in the project created in data processor 800
In document.System 820 can use user interface system, and the first software application of its Computer is created and edited scalable
Font, computer transmission scalable font can contract to electronic laser element (for example, in project document), the use of electronic laser element
Font is put to convert text data to the image for laser printing.
Fig. 9 is shown with the technology of scalable font marker material.Receive the corresponding mark for being used for material by laser beam
Character and quality information 900.This can be related to regulation character together with character size (for example, in project document of preservation)
Come the user printed.This relates to show in advance quality for tagging items (e.g., including in the project document of preservation
The quality settings of middle acquiescence) user or show quality (for example, the input user related to laser on line connects during work operation
The new quality settings of mouthful device) user.Pay attention to, quality settings can be the pixel interval value directly set in part, or can
To be certain value (boolean, more classification, or lasting) for typically showing printing quality.Obtain the font defi-nition of regulation character portion
(for example, independently of pixel compartments) 905.This can include response user and show the input of font defi-nition (for example, user's selection includes
The project document of the preservation of font defi-nition as defined in past) from memory be loaded into font defi-nition.Alternatively, font defi-nition can be straight
Connect and inputted by user.
The position 910 at one group of multiple interval is produced from character field according to character and quality information.This can include be based on from
The quality settings (for example, from the value for being supplied to the mark quality slider interface of user to receive) that user receives are one in character portion
Cause ground spaced-apart locations.For example, the consistent interval of position can use the pixel separation from user to input to determine that where is placed
Position for the laser residence in character portion.Pay attention to, can also input in place from the quality settings based on other factorses
The interval put.For example, specific quality settings can cause the first amount of space being used in horizontal and vertical straight line portion,
(pay attention to, the pixel separation on diagonal typically needs than the straight line portion of equal length in diagonal straight line portion
40% more laser dosage obtain similar quality) second (more typical) amount of space, and used in given character
The overlapping straight line portion of other straight line portions in the 3rd (more uncommon) amount of space.
Furthermore, it should be noted that in itself can be from one group of base to the pixel compartments of laser residence position for converting character portion
Selected in quality settings, obtainable pixel compartments.For example, two pixel compartments can be obtained in some embodiments
(32x20 and 64x40), when quality settings are more than threshold value, system can select larger pixel compartments.Alternatively, it is not necessary to pre-
Multiple pixel compartments are defined, but multiple pixel compartments can be produced based on quality settings value and character size as needed.
It can determine what lattice size used by the size of the LASER SPECKLE of system.Lattice should be sufficiently large so as to when mark pair
During linea angulata, adjacent pixel will be overlapping on that line.For example, by specified spot size 0.18mm, mark 2mm is high, 1.2mm is wide
Character, 11x9 fonts cause 0.16mm perpendicular separation and 0.12mm horizontal interval.Two values are both less than nominal spot chi
It is very little.But the pixel on diagonal wire tag can be spaced 0.22mm, more than threshold value.Increase lattice size, for example, 40x25, to disappear
Except the problem.Another driving factors of the determination of lattice size can be the complexity of character.More details typical cases need more
High resolution ratio.When mark non-latin script character, such as during Japanese, this point can be especially important.
It is also to be noted that by allowing laser to be the multiple spots of each position mark, for true using given pixel case marking
Fixed position can correspond to following pixels in itself, and these pixels are more than the spot diameter of laser.The atomization of the mark position
(atomization) in some embodiments can be directly by user's control, and in some embodiments can be by matter
Amount sets input to be controlled.
In any case, in the case of laser beam is not released, stopped by guiding laser beam in position and between position
It is mobile, using laser beam to material marking 915.Therefore, distribution repeat, variable residence time laser printing processes can be with word
Body defines Combination of Methods to produce the dosage unanimous on the whole on mark.Pay attention to, term " stop " is meant when sharp in the present context
Light at least slows down close to the laser during position that form mark, but need not stop completely；It is appreciated that quality settings are in itself
The amount and essence of residence time in position can be influenceed.
(it can be somebody's turn to do by using font defi-nition is developed to dot matrix laser labeling method from TrueType and other fonts
Font defi-nition is partly to define font).This can be completed in a manner of creating consistent point interval.Therefore, it is possible to use independent word
Body is defined to produce the multiple Step-and-repeat laser sequences exported to consistent dosage, vector expression quality from the output of low quality dot matrix
Row.
Figure 10 A -10C show the example of the character obtained according to scalable font.As shown in Figure 10 A, the word of alphabetical " E "
Body, which defines 1000, includes four straight line portions.Based on the quality settings of the character are obtained, 64x40 output lattice are selected and at this
64x40 is exported distributes mark position to every four pixels to obtain one group of position 1010 in lattice.As shown in Figure 10 B, work as increase
Quality settings, it is possible to reduce for the interval between the pixel of mark, obtain one group of position 1020.As shown in fig 1 oc, work as matter
Amount set from the quality settings in Figure 10 A reduce when, can instead select 32x20 to export lattice, execution position can be distributed to 32
× 20 export every three pixels in lattice so as to obtain one group of position 1030.In addition, the sequence between each several part can also pass through
Font provides.
Figure 11 shows another example of the character obtained according to scalable laser font.The font defi-nition 1100 of alphabetical " N "
Including three straight line portions.Quality settings based on the character, select 50x50 output lattice and in 60x60 exports lattice to be vertical
Directly distribution mark position in part, which gives every six pixels and distributes to every four diagonal pixels for diagonal part, (corresponds to six
The same distance of vertical pixel), to obtain one group of position 1110.Therefore, the pixel separation being consistent for diagonal.By changing
Become x and y-axis (for example, y increments are 6 in vertical component, only has substep size 4) to complete this point on diagonal.
In some above-mentioned examples, incomparable inconsistent pixel separation is used near character portion crosspoint.Allow what this put
Criterion can be based on determining whether interval is more than nominal spot size.If interval is larger, then non-uniform pixel generally will not
Generation problem, because these lines will not actually interlock.If interval is smaller, the pixel in crosspoint can be abandoned.Pay attention to, when
On thin stock, such as thin layer, during printing, crosspoint can be particularly importantly minimized.
In some embodiments, the beginning and end of character portion can be placed so that it is guaranteed that their accurate positions,
Remaining pixel can be evenly spaced between them.This can cause to be introduced into minor error into pixel separation, among it every
Can be slightly more or less than required value, but this is probably preferable in some embodiments.In addition, font defi-nition can be with
Including a part, in such a case, it is possible to which mobile laser arrives defined position (zooming to pixel compartments) and keeps at that (or subtracting
Speed) residence time.
In addition, in some embodiments, font defi-nition can include curved portion.Curve (such as three-dimensional Bezier curve)
Can be by combining a series of straight line portions come approximate.Some known technologies, such as de Castlejau's algorithms are (see http:
www.antigrain.com-research-adaptive_bezier-index.htm).Once it is divided into straight line portion, with given
The adequate resolution of pixel compartments, these curves can be handled as handling other straight line portions.When scale characters, this is lighted
Basic effect, obtain straight line portion from each curved portion here provide character scale to any size curve outward appearance.
Therefore, laser code system can be designed to allow user's design to include the coding of one or more characters, one
User can specify that font, size and the quality of each character in coding in individual or multiple characters.Font determines character substantially
Shape.Quality settings can determine to form the consistent interval of the pixel of character.Low quality set, character by wide interval picture
Element composition.When user improves quality, pixel count increase, but because character size keeps identical, pixel is more compact.Certain point
(by laser beam specified spot size and stock to laser in response to determining that), pixel starts overlapping on the substrate.This point
Define high quality threshold value.In the threshold value and during more than the threshold value, printing is no longer presented dot matrix printing, but with similar in appearance to vector
The quality of Mk system.Unlike other dot matrix laser marking systems, same font can be used for printing different sizes and quality
Character.
Although the application is carefully described, it is to be understood that without departing substantially from as the application described in accessory claim
In the case of spirit and scope, various changes, combination, replacement and change can be made.
